retrieve cpu and memeory information
Hi all
can someone please tell me how to get the folowing information on Linux and SunOS using shell command (if it's possible):
services (deamons) - name , type and status
Memory - memory type , total size
CPU - cpu type and cpu family
for example : for Linux using "free -o| tail +2| awk '{print $2}'| head -n 1" will retrieve the total size of memeory.
Thanks

>Memory
Type of memory is not of any interest for a real OS, so UNIX/linux does not have programs for that ;-)
>CPU
Linux% grep '<.>CPU:' /var/log/boot.msg
Solaris% uname -im
>SERVICE
> .. can I know the status of each process
Linux% see that STAT column of ps output
Solaris% see S column of output
> .. or even the start type
this is of no interrest at all in UNIX/Linux.
A deamon is either running or not. Dot. There is no difference if started by inetd, any startup script at boot time, or manually from within a shell by a user.
If you want to which deamons may be started automatically, just have a look at the scripts in
Linux% /etc/rc[12345].d or /sbin/rc[12345].d
Solaris% /etc/rc[12345]
(the number 1..5 indicates the runlevel of your machine)
and grep -v ^# /etc/inetd.conf

Hi ahoffmann
>CPU
Linux - I tried the line grep '<.>CPU:' /var/log/boot.log
and I get : "grep: /var/log/boot.msg: No such file or directory" error message , is there any other file I should get it from there ?
Thanks Danny

I cannot answer for Linux,
But in Solaris, you can use the program
prtconf program (in my system, it is in /etc/ )
Here is the clipping from the MAN page:
==========================
NAME
prtconf - print system configuration
SYNOPSIS
SPARC
/usr/sbin/prtconf [ -V ] | [ -F ] | [ -x ] | [ -vpPD ]
IA
/usr/sbin/prtconf [ -V ] | [ -x ] | [ -vpPD ]
DESCRIPTION
The prtconf command prints the system configuration information. The output includes the total amount of memory, and the configuration of system peripherals formatted as a device tree.
==========================
Hope this helps,
sincerely,
dBalaski

I'llgive it a try as well :
Cpu -
linux cat /proc/cpuinfo
solaris psrinfo -v
Mem -
Linux cat /proc/meminfo
Solaris prtconf |grep Mem
as for services and demons
Linux - chkconfig --list
Solaris - go through the rc3.d scripts
all linux commands are tested on redhat ....

>Memory
I want to know if it's possible to get the type for example: if the memory is DRAM,SRAM,VDRAM...
and about the size , yes thats what I need.
>CPU
I need to know the type of processor (Centeral processor,Math processor,...)
about family I need to know if it is Pentuim II , petuim III,8086,8088,....
>SERVICE
it looks fine what you gave me , can I know the status of each service (running,stop) or even the start type (automaticaly,manual...).
Thanks
